Hemophagocytic lymphohistiocytosis is a rare, aggressive and life-threatening syndrome of excessive immune activation. Secondary hemophagocytic lymphohistiocytosis (sHLH) is the most common form of this disease and is typically associated with several other clinical conditions (eg, malignancy associated HLH (mHLH), infection, or autoimmune disease). ELA026 is a fully human immunoglobulin G1 (IgG1) signal regulatory protein (SIRP)-directed monoclonal antibody designed to deplete the myeloid and T cells driving the inflammation. The purpose of this study is to assess the safety, efficacy pharmacokinetics and pharmacodynamics of ELA026 in participants with sHLH. Type: Interventional Start Date: May 2022 |

This phase II/III trial compares the effect of adding durvalumab to chemotherapy versus chemotherapy alone before surgery in treating patients with upper urinary tract cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as methotrexate, vinblastine, doxorubicin, cisplatin, and gemcitabine work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Durvalumab in combination with chemotherapy before surgery may enhance the shrinking of the tumor compared to chemotherapy alone. Type: Interventional Start Date: Nov 2021 |

This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to compare the usual treatment (radiation therapy with cisplatin chemotherapy) to using radiation therapy with docetaxel and cetuximab chemotherapy, and using the usual treatment plus an immunotherapy drug, atezolizumab.

This phase II/III trial tests the safety, side effects, and best dose of the drug cabozantinib in combination with standard chemotherapy, and to compare the effect of adding cabozantinib to standard chemotherapy alone in treating patients with newly diagnosed osteosarcoma. Cabozantinib is in a class of medications called kinase inhibitors which block protein signals affecting new blood vessel formation and the ability to activate growth signaling pathways. This may help slow the growth of tumor cells. The drugs used in standard chemotherapy for this trial are methotrexate, doxorubicin, and cisplatin (MAP). Methotrexate stops cells from making DNA and may kill tumor cells. It is a type of antimetabolite. Doxorubicin is in a class of medications called anthracyclines. It works by slowing or stopping the growth of tumor cells in the body. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Adding cabozantinib to standard chemotherapy may work better in treating newly diagnosed osteosarcoma.

This clinical trial tests the impact of a culturally-tailored home-based physical activity program on physical fitness in Hispanic or Latino/Latina adolescent and young adult (AYA) childhood cancer survivors. After treatment for cancer, some AYA survivors experience long-term effects from the cancer and its treatment including weight gain, fatigue and decreased physical fitness. Hispanic or Latino/Latina survivors may have a higher risk of these effects compared to non-Hispanics. Regular physical activity helps maintain healthy weight, energy levels and overall health.

The goal of this study is to learn if a decision aid (DA) website helps people with thyroid cancer make informed decisions about radioactive iodine (RAI) treatment. The main questions it aims to answer are: - Does the decision aid help participants understand the risks and benefits of RAI treatment? - Does it help participants make choices that reflect what matters most to them? - How does the decision aid compare to usual care in supporting patients through this decision? Participants who have been recently diagnosed with intermediate-risk differentiated thyroid cancer (DTC) will be randomly assigned to one of two groups. One group will receive a special decision aid website. This site includes detailed information about RAI, short videos, drop-down menus with extra details, exercises to help clarify values, and tools to help patients prepare questions for their doctor. The other group will receive the American Cancer Society (ACS) website. This site gives basic information about RAI but does not include interactive tools and is not specific to intermediate-risk thyroid cancer. Follow up surveys will be sent to the participants periodically, first at the start of the study, and again at 1 week, 4 weeks, and 6 months later. Researchers will compare how the two groups differ in making informed decisions. The decision aid is meant to support, not replace, a conversation with the medical team. Doctor recommendations remain an important part of treatment decisions. Type: Interventional Start Date: Aug 2025 |

This study evaluates cancer-related weight and muscle mass loss, symptoms, and physical function (cachexia) in patients undergoing treatment for colorectal, lung, or pancreatic cancer that cannot be removed by surgery (unresectable) or is stage IV. Patients with these cancer types are at risk for developing cancer cachexia (CC), which is defined as weight loss, muscle loss, and fat loss due to cancer. CC has been associated with reduced physical performance, impaired quality of life, and poorer survival. Many studies that have evaluated treatments for cancer-related weight and muscle loss have aimed to treat all patients with weight loss exactly the same and, unfortunately, have not been successful. Like different cancer types, weight and muscle loss related to cancer may have different causes in different individuals and the best treatment strategy for this condition may not be a one-size-fits-all approach. Information gathered from this study may help researchers develop new diagnostic criteria for CC and design better treatments and clinical trials for cancer-related weight and muscle loss in the future to improve the quality of life in patients with advanced colorectal, lung, or pancreatic cancer.
